WELL-CLEANER.

Application filed December 22, 1913.

This invention comprehends certain new and useful improvements in well cleaners and has for its primary object to provide a device which may be readily placed in position in a well after the removal of the pump, for the purpose of cleaning the sediment from the bottom of the well.

Another object is to provide a device of this character which will be of extremely simple construction and operation, and composed of the minimum number of parts.

A further. object is to generally improve and simplify the construction and operation of devices of this character and increase the efliciency thereof without materially increasing the cost of the same.

With the above and other objects in view, my invention consists in certain novel constructions, combinations, and arrangements of parts to be hereinafter more fully described, claimed, and illustrated in the accompanying drawings, in which Figure 1 is an elevational view of the complete device in position in a well of a conventional form, said well being shown in longitudinal section; Fig. 2 is a longitudinal section of the lower portion of the de vice; Fig. 3 is a transverse sectional view thereof, on the line 33 of Fig. 2.

Referring more particularly to the drawings in which similar reference characters designate corresponding parts throughout the several views, 1 designates the discharge pipe having the spout 2 projecting laterally therefrom near its upper end.

The lower portion of the discharge pipe 1 is enlarged, as shown at 3 and has the suction cup 4 formed on its lower extremity by flaring the lower end, as will be clearly understood by referring to the drawings.

Adjacent the upper portion of the enlarged lower end 3 of the discharge pipe 1, I have provided a valve seat 5 upon the upper face of which the flap valve 6 is engaged, said valve being secured in position by the hinge 7.

Within the enlarged lower end 3 below the Specification of Letters Patent.

Patented Dec. 29,1914.

Serial No. 808,253.

valve seat 5 is positioned the reciprocating hollow piston 8 having the flap valve 9 engaged upon its upper face, as shown at 10. The piston 8 is secured upon the upturned lower ends 11 of the reciprocating rods 12 which are engaged through the guide openings 13 at the top ofthe suction cup 1 and which have their upper ends secured to the rod 141 to which, in turn, are connected the inner ends of the operating levers 15, said levers 15 being pivoted upon the pins 16 mounted on the upper ends of the supporting arms 17. The supporting arms 17 are,

in turn, secured to the collars 18 fastened around the upper end of the discharge pipe 1, it being understood that the upper end of the discharge pipe is closed.

From the foregoing it will be readily seen that as the operating levers 15, which extend in opposite directions, are operated, the reciprocating rods 12 will be reciprocated, thereby imparting a like movement to the reciprocating hollow piston 8, causing the flap valve 9 to close upon upward movement of the piston 8, thereby drawing or sucking the water from the well around and beneath the edge of the suction cup 4 and upwardly in said suction cup and into the discharge pipe 1, the flap valve 6 opening as the water is forced upwardly past the same, and again closing upon downward movement of the piston 8, the flap valve 9 opening upon said downward movement of the piston 8. This operation of the device causes thorough agitation of the water in the well, thereby loosening the sediment at the bottom of the well and forcing the same upwardly in the discharge pipe 1 to be discharged by way of the disclharge spout 2, thoroughly cleaning the wel While I have shown the preferred e1nbodiment of my invention, it will be readily apparent that minor changes in the details of construction and arrangement of parts may be made within the scope of the appended claim without departing from the spirit of my invention or sacrificing any of the advantages of the same.

What I claim is A well cleaner including a discharge pipe, a flared suction cup formed on the lower end thereof, guide sleeves formed on the opposite sides of the pipe at its lower end and communicating with the interior of the suction cup, a valve seat formed in the discharge pipe adjacent its lower end, a flap llu valve connected to the upper face of the seat, a valved piston slidably mounted within the Copies of this patent may be obtained for the operating rodsrand saidsuction cup being of such a length that the lower ends of 15 g the rods will be prevented from engagement against the bottom of the well when said rods are disposed at their lowermost point during the reciprocation thereof.

Intestimony whereof I hereunto aifix my 20 signature in the presence of two witnesses.
